I wonder what name his kids use at school when the subject of kids dads comes up (maybe parents/teachers meetings). Surely the Nakamoto children don't use Satoshi? Maybe Sam, or Steve, possibly Sheldon?
Since the name covers up the group which is believe to be behind Bitcoin development, it’s not an official name that children needs to answer in school like their surname, and beside someone who is determined to hide their identity even their children won’t be spare with such information they won’t have access to that and won’t even know if their parent are the creator or is the creator of Bitcoin, if Satoshi was a real name it could have been possible to try to link to to everyone who bare that name.
